Iris after blooming
The blooms on the iris plants are dead, stalks still standing, as is the foliage. [I don't think they bloom more than once in spring.]
Do I have to wait for the stalk to die to cut back? And can I cut back the foliage too? And do I have to wait for that to die as well? It is taking up a lot of room in garden...I would like to slip a few annuals in for color during the summer.
Any insights much appreciated...
